So i have an 87 bronco ii, i replaced the heads about 2 months ago, it runs ok but has a weird idle problem. It will idle fine for the first 5 minutes, then bog down. After driving it some, when i come to a stop, the rpms go up, then drop, then go up then drop. It will eventually try to even itself out, but that only lasts about 5 minutes then its back to the up and down.
Another problem, which might relate to the idle problem, when i first start to go after starting the truck from cold, it will cut out and if i don't let off the gas it will die. It does it once or twice then goes away when it gets a bit warmed up.
Here is a vid of the problem (sorry for the quality, recorded it on my phone)
